build method
Builds the IconTab widget, rendering an IconButton that responds to the current selection state propagated via Pylon.
This method queries the widget tree for the _IsSelectedBottomIndex state
using PylonOr to determine if the tab is selected. It then constructs an
IconButton with the appropriate icon (selected or default) and applies
primary color from ArcaneTheme for visual feedback. The onPressed callback
is wired to handle user interactions, facilitating seamless navigation within
the Arcane UI ecosystem.
Returns a fully interactive IconButton widget ready for embedding in a ButtonBar.
Implementation
@override
Widget build(BuildContext context) {
bool selected =
context.pylonOr<_IsSelectedBottomIndex>()?.selected ?? false;
return IconButton(
onPressed: onPressed,
icon: Icon(selected ? (selectedIcon ?? icon) : icon,
color: selected ? Theme.of(context).colorScheme.primary : null),
);
}
